Definitions

  • This invention is related in general to the field of telecommunications equipment. More particularly, the invention is related to signal transfer point local number portability database audit system and method.
  • LNP Local number portability
  • NPAC number portability administration center
  • LSMS local service management system
  • NPAC SMS Interoperability Interface Specification document prepared for the North American Number Council contains the information model for the NPAC and SMS mechanized interfaces.
  • SMS and STP typically CMIP/CMISE protocol is used, where CMIP/CMISE messages containing LNP data are exchanged between a software process called object manager running in SMS and a software process called object agent running in STP.
  • the signal transfer points are configured as mated pairs to operate in a load-sharing manner and to provide redundancy. Therefore, the local number portability databases maintained by mated pairs should contain identical data.
  • the data in a local number portability database maintained by one signal transfer point may not match the data at its mate.
  • Failures which may cause a data mismatch includes link failure between the local service management system and one of the signal transfer point nodes, hardware or software failure at one of the signal transfer point nodes, power failure at one of the signal transfer point nodes, or software/hardware maintenance, diagnosis, or upgrade during local number portability data update. Further, data mismatch may be caused by extended delays in data update request between the local service management system and one of the signal transfer points.
  • a method of auditing a first local number portability database associated with a first signal transfer point includes sending, by a first audit manager, a request to the first signal transfer point, the request specifying at least one ported telephone number.
  • a first audit agent receives the request at the first signal transfer point, looks up the specified at least one ported telephone number in the first local number portability database, and obtains at least one corresponding local routing number.
  • the first audit agent then sends the at least one corresponding local routing number to the first audit manager.
  • the audit manager compares the received at least one corresponding local routing number to data local to the first audit manager. The audit manager then reports the result of the comparison.
  • an automated method of determining data discrepancy in first and second mirrored databases includes sending, by a first audit manager, a request to access specific entries in the first database.
  • a first audit agent associated with the first database then receives the request, looks up the specified entries in the first database, and obtains data corresponding thereto.
  • the first audit agent sends the data to the first audit manager.
  • the audit manager compares the received data to data previously-obtained by the first audit manager, and reports the result of the comparison.
  • a signal transfer point local number portability audit system includes an audit manager operable to compose and send an audit request message to an audit agent associated with a first local number portability database.
  • the audit request message specifies at least one ported telephone number.
  • the audit agent is operable to receive the audit request message, look up the specified at least one ported telephone number in the first local number portability database, and composing and send an audit response message to the audit manager.
  • the audit response message includes at least one local routing number corresponding to the specified at least one ported telephone number.
  • the audit manager is operable to receive the audit response message, and compare the received at least one local routing number with at least one local routing number accessed from a second local number portability database. The audit manager then generates a report on the result of the comparison.
  • FIGURE 1 is a simplified block diagram of the telecommunication network 10 according to an embodiment of the present invention.
  • Telecommunication network 10 includes an operational support system (OSS) 12 which encompasses a local service management system (LSMS) 14 coupled to a number portability administration center (NPAC) 16.
  • Local service management system 14 may also be referred to as an element manager (EM).
  • Local service management system 14 is coupled to at least one mated pair of signal transfer point nodes (STP0 and STP1) 20 and 22 via some network links 18.
  • STP0 and STP1 signal transfer point nodes
  • network links 18 are CMIP/CMISE (common management information protocol/common management information service element) over TCP/IP/Ethernet (transmission control protocol-Internet protocol/Ethernet) network links but other protocols may be used.
  • CMIP/CMISE common management information protocol/common management information service element
  • TCP/IP/Ethernet transmission control protocol-Internet protocol/Ethernet
  • Signal transfer point 20 includes a processor or computing platform 24, on which an audit manager process 26 (a CMISE/CMIP object manager as in LSMS) is executing.
  • Signal transfer point 22 is the mate of signal transfer point 20.
  • Signal transfer point 22 also includes a processor or computing platform 28.
  • An audit agent process 30 (a CMISE/CMIP object agent) executes on processor 24 and responds to requests from auditing process 24.
  • the object agent process could be the same as the one that responds to Object Manager in SMS, or could be a different process with different priority if real-time impact is a concern.
  • a local number portability database 31 also resides on processor 24.
  • the signal transfer point mated pair operates on a load-sharing basis so that both signal transfer points 20 and 22 operate actively and concurrently to share the workload. Because both signal transfer points handle incoming ported telephone number translation requests concurrently, their respective databases must be synchronized and have matching data.
  • NPAC 16 sends local number portability ported telephone number update requests to local service management system 14, which in turn dispatches the update requests to signal transfer points 20 and 22 under its control and management.
  • the failure conditions may include network link failures that results in an update request being delayed or not reaching one of the signal transfer points, and hardware or software malfunction, maintenance, or upgrade at one of the signal transfer points. This failure may result in data mismatch between local number portability databases 27 and 31.
  • Audit manager 26 and audit agent 30 are processes that perform audits to detect data mismatch between the databases according to the teachings of the present invention.
  • FIGURE 2 is a flowchart of an audit method or process 40 according to an embodiment of the present invention.
  • Audit process 40 may be invoked by a user-issued command on the command line or may start automatically at a predetermined time, executed in a periodic manner for maintenance or diagnosis, or executed whenever auditing is desired. For example, daily audits may be scheduled to take place when network traffic is at a minimum.
  • block 42 the nature of the audit is determined.
  • An audit may be a full audit covering all ported numbers, or a partial audit covering a certain range of ported numbers, or a recent change audit covering those recently changed by consulting a record or log maintained by audit manager 26 or by another process at signal-transfer point 20.
  • the log may be an existing update request log maintained at each signal transfer point, which is a circular buffer of a predetermined size that records the most recent update requests from the local service management system.
  • a more reliable method may be to copy all un-audited ported telephone number updates from the existing update request log to a second log before being overwritten. Un-audited entries in the update request log may be determined by comparing its time stamp with the start time of the last audit.
  • an audit may be checking all the fields of attributes of LNP data entry, or just checking certain fields or attributes (e.g. only LRN, or only GTT). Moreover, an audit may be checking only LNP data entries meeting certain criteria, for example all LNP data entries with a certain LRN.
  • a M-GET CMIP/CMISE message is composed of the ported telephone number(s) or range of ported telephone numbers (TNum), and the IP address of processor 28 at signal transfer point 22. If signal transfer point 22 has more than one processor, the IP address specifies the destination processor on which audit agent 30 resides. For example, signal transfer points 20 and 22 each typically includes at least two processors operating in active-standby mode. The IP address specifically identifies the destination processor. Other CMIP/CMISE message parameters may also be included but are not relevant to the discussion herein.
  • Audit manager 26 composes and sends the M-GET message to audit agent 30, as shown in block 46 in FIGURE 2.
  • the M-GET message includes an IP address of the destination where audit agent 30 resides, and one or more telephone numbers, or a range of telephone numbers.
  • the M-GET message is received by audit agent 30 and requests the audit agent process 30 to responds.
  • Audit agent 30 analyzes the M-GET message and determines which telephone numbers the audit manager is interested in auditing.
  • Audit agent 30 looks up, in its local number portability database 31, the ported telephone number or numbers specified in the M-GET message and composes one or more M-LINK messages containing the local routing numbers and GTT corresponding to the specified ported telephone numbers.
  • Each M-LINK message may contain a predetermined number of LNP data entries. Therefore, if the request exceeds the predetermined number, additional M-LINK messages are composed and sent.
  • Audit agent 30 composes and sends the M-LINK messages to audit manager 26.
  • the M-LINK message includes the IP address of processor 24 and the LNP data entries requested by audit manager 26.
  • audit manager 26 receives the M-LINK messages and compares the returned LNP data entries with the data stored in its own local number portability database 27.
  • audit agent 30 sends a M-GET message reporting whether the process was successful or failed, as shown in block 52.
  • a report (such as an IPR or information problem report) or some form of notification is then generated by audit manager 26 to indicate whether a data mismatch was detected by the audit, as shown in block 54.
  • the report may be printed, stored in a predetermined location, or transmitted to a predetermined recipient or processor, or invoke a certain software program for automated corrective actions.
  • the method of transmission may be by electronic mail, by facsimile, by paging or any other form of communication to a craft.
  • the form of transmission may be determined by the extent of data mismatch. For example, if the number of mismatched data is great, a craft may be notified immediately by paging. It is noted that due to LSMS update request propagation delays, LNP data entries may be changed at slightly different times at the mated STP pairs. Therefore, if a mismatch is detected, a second check on the very LNP data entry may be performed again after a certain time window before a mismatch is declared.
  • data mismatch may be one of three types from audit manager perspective: missing data, extra data, or content-different data.
  • unidirectional audit where the audit manager resides on one signal transfer point and auditing the data in the second signal transfer point, all three types of mismatch can be correctly detected for full audit and partial audit because audit manager is able to specify a range of LNP data entries.
  • the invention also contemplates having audit managers and audit agents resident at both signal transfer points to enable bi-directional audit.
  • the audit manager may be resident in a third network node, such as at the local service management system, which compares data received from both signal transfer points.
  • CMIP/CMISE messages as described above is provided as an example and is currently preferred because this is the format presently used for local number portability data update requests between local service management system 14 and signal transfer points 20 and 22. Therefore, each signal transfer point already possess an agent process residing thereon for responding to data update requests from a CMISE manager residing on local service management system 14. Further, the inclusion and use of an audit manager 16 which communicates with a preexisting audit agent 30 enables a quick and straightforward implementation of an audit system and process because the approach requires no new hardware, no new software in audit agent and only a small amount of new software at audit manager for user interface into the CMISE/CMIP Object Manager software.
  • the present invention also contemplates using another communication protocol and message format to accomplish the audit (for example, using message compaction, or sending LNP data checksum instead of each LNP data entry).
  • the path of communicating the audit messages may be direct link 32 rather than network 18.
  • audit manager 26 may reside outside of a signal transfer point, such as a third network node having a connection to the signal transfer point mated pair.
  • the audit manager may reside on the local service management system and be used to audit plural mated pairs of signal transfer point local number portability databases and compare with the database at the local service management system or comparing the data received from the mated pairs.
  • the audit manager and audit agent may be platform-independent object-oriented processes that can be deployed on computing platforms.
  • the communication mechanism described herein, the CMISE/CMIP messages, are standardized and specified by ITU.
